Honestly judging from the volume of his output, a ton.

It’s rare to run into prodigious artists who simply produce a few perfect pieces - as a rule those few magnum opuses are built on a hill of cutting room floor scraps.

The director James Cameron stands out because he has only produced huge box office hits. Extremely hard to do like you said, and most artists and auteurs would be happy to have one great work they can be remembered for, even if it's amidst a dozen forgettable pieces.

He's only published blockbuster hits. But I'm sure he has lots of practice films that have never seen the light of day?

Sometimes the forgettable pieces come later. In JC's case, that's Avatar 2

Don't let your personal love of Piranha II convince you that it was a box office hit.

And then there are those like J.S. Bach.

I don’t know how to feel about HN thinking one of the greatest artist of all time produced slop. You guys really think Leonardo davinci was drawing ladies with 6 fingers before the Mona Lisa?

I assure the worst of Shakespeares work is far beyond anything most writers can produce, much less the incoherent slop LLMs generate
